Installation Instructions

  1. Use the collar assembly as it is – do not clean, lubricate, or otherwise alter except as instructed in this document, but remove incidental dust or debris before assembling.
  2. Disassemble the plastic shroud by unscrewing the two halves, remove the internal metallic collar, and discard the foam shipping material.
  3. Remove the three O-rings from their package and lubricate with the provided lubricant. Wipe off any excess lubricant, being sure to leave an even film. Save the excess lubricant for use in the assembly process.
  4. Seat the two smaller O-rings into the internal bore grooves found on each half of the plastic shroud.
  5. Install the remaining large O-ring into the external groove on the shroud half with the male threads.
  6. Wipe the bore of the metallic collar clean and apply a thin film of the lubricant provided with the O-rings.
  7. Determine the proper orientation for the assembly based on the application. The shroud half with the external threads and O-ring should be positioned nearest to the applied load for proper performance.
  8. Assemble the metallic collar into the male half of the shroud by making sure that the face groove on the collar faces towards the shroud and then aligning the two positioning pins on the shroud with the corresponding holes on the face of the collar. If installed properly, the screw access notch should line up with the socket screw and the shroud should run true with a consistent amount of the metallic collar exposed on all sides. If not, ensure the pins are seated fully, and there are no contaminants between the collar face and the shroud.
  9. Slide the partial assembly onto the shaft and into the desired position. If the assembly is against a bearing face, apply any preload that is necessary.
  10. Tighten the socket screw to the recommended seating torque using a hex wrench.
  11. Slide the female half of the shroud onto the shaft towards the assembly and thread the two halves together to seal. If the male shroud is not held in place against a surface, assembly is most easily accomplished by gripping the shaft with a fist behind the male shroud and pressing against the collar with one hand and twisting the female shroud on with the other. HAND TIGHTEN ONLY.
  12. Wipe off any excess lubricant that remains on the shaft or surface of the assembly.
